Answer:

Angle of reflection will be
$40^(\circ)$

Step-by-step explanation:

We have given angle of incidence from the smooth surface is
$40^(\circ)$

So angle of incidence =
$40^(\circ)$

We have to find the angle of reflection

From l;aw of reflection we know that angle of reflection is equal to the angle of incidence

So angle of reflection will be equal to
$40^(\circ)$
